Genomic location of stripe rust resistance in a hexaploid derivative of durum wheat Glossy Huguenot and development of closely linked markers.

ABSTRACT: Stripe rust, caused by Puccinia striiformis f. sp. tritici (Pst), is a devastating fungal disease that affects wheat production in many regions of the world. The identification and characterisation of new sources of host plant resistance is required to enrich the existing gene pool. Durum wheat landrace Glossy Huguenot showed high level of resistance to stripe rust in the field. To utilise this resistance in wider wheat germplasm, we transferred it to common wheat cultivar Westonia. A backcross₂F₅ (BC₂F₅) line (WGH54) which showed high levels of all stage resistance against the then prevalent Pst pathotypes was crossed with the susceptible parent Avocet S (AvS) and F_2:3 generation was raised. Monogenic segregation was observed among WG
